Transforming a large list into a string

Hi there

I am getting an error from the block “make text from list”: Error: Data truncation: Data too long for column 'grades' at row 1 at new ResponseError Is there a different way I should approach it when I want to transform a large list into a string?

This is the list:
12:50:13.728 | SERVER_CODE | INFO | [20671] ESL A2,ESL A3,ESL B1,ESL B2,ESL B3,ESL C1,ESL C2,Grade 1,Grade 10,Grade 11,Grade 12,Grade 2,Grade 3,Grade 4,Grade 5,Grade 6,Grade 7,Grade 8,Grade 9,Kindergarten,Spanish A1,Spanish A2,Spanish A3,Spanish B1,Spanish B2,Spanish B3,Spanish C1,Spanish C2,Spanish C3

Hello @Andreas_Marinopoulos

Thanks for posting this topic.
I just tried to run the request and it returns me

400 - Cannot read property 'data' of null

Yes @vladimir-upirov , you need to invoke a specific object to replicate it, I am sending it to you on Slack.

I see,

The error says that you are trying to save a Users object where grades property is more than 250 characters

I can propose you change the column maxSize to 500, or change type from String to Text

Thank you, I will try that
